Carphone Warehouse woes

I recently bought a new phone from Carphone Warehose, so as a result traded in my Samsung S9 (very old now I know!) as they offered £140 + £100 bonus. Today I got an email that they offer only £35 as it has screen burn. The phone was in excellent condition as it was well taken care of. I was wondering if anything else had the same issue with them, but somehow managed to convince them to still pay the original trade in value for it.

Can you tell me in the comments?

To be honest, I know most of these trade-in websites aren’t accurate. Places like this website compare recycler quotes but I am not sure how accurate they are in reality.

Some of the prices seem a bit suspect. What I really need to do is go for a SIM only type deal, I could get an iPhone 11 for about £300 from Music Magpie.  Why would anyone pay the £1000+ price for a new one (when they were new, of course…).

I can’t be bothered to even research what the iPhone 13 is about. I don’t want to spend £1400 on a phone, it’s a con. Plus places like Phones4U are no longer with us, sadly, since they went bankrupt.
